158 EXPERIMENT STATION RECORD. 



also by the State Swine Breeders' Association to swine breeders in the 

 State asking- their experience with the diseases. The replies show that 

 about 8 per cent of hogs perished each year that cholera prevailed, 

 and that the disease was most virulent where the hogs were allowed 

 free access to surface water and wallows. It is believed that medical 

 treatment is of little avail, although the U. S. Prescription, including 

 charcoal, sulphur, several sodium salts, and antimonj^ sulphid, was 

 as efficacious as any during the present season. As preventives are 

 recommended water from wells or springs, clean quarters, care in 

 feeding, and caution against infection by diseased hogs from other 

 sources. The Indiana laws relating to hog cholera are quoted, and the 

 answers received from the swine breeders of the State are condensed 

 and tabulated. 



The direct transmission of infectious entsro-hepatitis in tur- 

 keys, V. A. Moore {U. S. Dept. Agr., Bureau of A^iimal Industry Cir- 

 cular 5, pp. 8, figs. 7). — This briefly recounts the nature of the disease, 

 with illustrations of normal and diseased cfeca and livers, and gives the 

 result of experiments made to ascertain if the affection could be directly 

 transmitted from diseased to healthy turkeys. In ISTovember, 1895, 3 

 turkeys supposedly ill with this disease were shipped from Ehode Island 

 to this Department. One of the turkeys was dead upon its arrival, 

 but the other 2 were placed in the yard with 6 healthy turkeys. The 

 dead turkey was found vq}on post-mortem to be aiiected with the dis- 

 ease, and microscopical examination revealed the presence of the sjDe- 

 ciflc protozoan parasite. The liver and ca^ca of the dead turkey were 

 chopped up and fed to the healthy ones. In addition, the feces of the 

 other turkeys suspected of having the disease were mixed with the food 

 given the healthy turkeys. One of the Ilhode Island turkeys died from 

 the disease 4 days after its arrival and its viscera were fed to the other 

 turkeys. In the 6 weeks following 3 of the healthy turkeys became 

 affected with the disease, and died from it. In January the remaining 

 3 were killed and one of them showed evidence of the disease. The 

 third of the turkeys received from Khode Island showed no symptoms 

 of the disease and neither died nor was killed. The experiment is 

 believed to be a conclusive proof of the communicability of the disease 

 by the association of diseased turkeys with healthy fowls. 



Prevention of the disease by the destruction of sick turkeys is 

 strongly recommended and the complete disinfection of infected locali- 

 ties urged, the cleansing to be done by the use of slacked lime in 

 turkey yards and the washing of infected jilaces with the following: 

 Crude carbolic acid, ^ gal. ; crude sulphuric acid, h gal. ; water, 19 gal. 



Tuberculosis, F. W. Brewer ( Utah Sta. Bid. 41, pp. 37, pis. 2, 

 figs. 5). — This bulletin gives a popular and general discussion of the 

 subject of tuberculosis, both of animals and man. The nature of the 

 bacillus is discussed and the formation and appearance of tubercles 

 briefly described. The method of injecting tuberculin into suspected
